The Norwegian JIA Study (NorJIA):

NorJIA is a prospective, multicenter, observational study of 228 children with juvenile idiopathic arthritis (JIA) and 224 controls attending the university clinics in Bergen, Tromsø and Trondheim. The study will run over 5 years, and include extensive clinical, laboratory, radiological and oral examinations at baseline and after 2 years’ follow-up. There will be a special focus on the temporomandibular joints (TMJs) with extensive imaging (MRI 3Tesla, ultrasound, OPG, CEPH, Bitewings and CBCT (small field of view (FOV) for TMJs)) and clinical TMJ examination, aiming at establishing scoring systems for active and chronic disease. The study is registered on https://clinicaltrials.gov/ with identifier: NCT03904459.
